ENDS 1.. S'TOLTZFUS, hub -LLZ /L/1,@WL,VVW. ISAAC 1;. MwL R UNITED STATES PATENT on ron I ENOS L. STOLTZFUS, OF GAP, AND ISAAC B. MILLER,'OF PARADISE, PENNSYLVAN DUMP-GAR AND OPERATING MECHANIEM.

To all whom it may concern:

Be it known that we, Enos L. SToLTzrUs and Isaac B. MILLER, citizens of the United States, residing at Gap and Paradise, respectively, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Dump-Cars and Operating Mechanism, of which the following is a specificatiomreference being had therein to the accompanying drawing.

Our invention relates to improvements in dump cars, means for operating the same, and means for returning the same to the main track.

Dumping-cars as constructed in the usual way are provided with removable sides or doors which require to be opened in various ways before the load can be deposited.

The objects of our invention are to obviate this and. other difficulties by providing; a dumping-car with only one closed end and means for automatically raising the rear end of said car, thus allowing its contents to escape through its open end and then bring ingsai'd car back into its normal position again.

Another object of our invention is to provide a durnpingcar of this class that may be coupled together in a train and each car oi the train dumped and returned to its normal position in an automatic manner and without any stoppage in the forward movement of the train.

While a further object of our invention is to provide a clumping-car and actuating apparatus in which the draft or pull is al- Ways on a level, no matter whether the car is loaded, in the act of dumping, or empty. With these and other objects in view our invention consistsin certain contraction and combination of parts as will hereinafter be fully described and claimed but it is fully understood that gvhile we have herewith described our invention as illustrated in the accompanying drawings forming part of this specification, we donot confine ourselves to the exact construction as shown, as slight changes may he made in the construction and combination of parts Without departing from the spirit of the invention.

In the drawings in which like reference characters indicate corresponding arts in all the views :-Figure 1, is a side elevation of a train of our improved cars and dumping apparatus showing one car on the main track before dumping, one car in the act of Specification of Letters Patent.

dumping and the other car retornin to its normal position upon the main trac after being dumped. Fig. 2, is a top plan view of the same, illustrating the out bearing dump Wheels, the coupling construction and the;v

general arrangement of the parts.

In the drawing, 1, indicates a main track which may be level and supported on a trestle asherevvith shown, or said main track 1, may be inclined at any suitahle'angle.

Parallel. to said main track 1, and outside of same are secured the inclined dumping rails 52, which are here illusti ated. as heinggoined at their upper ends to allow the cars to as cend on one side and descend on the other side; but said inclinedrail 2, may simply be inclined toward one direction and he provided with a suitahle stop at the upper end Said in 'ned. rails may he further 1 t of the car body forward end, and mounted upon any suitable I design of four wheeled truck, "with the e1;- ccption that the rear axle ii, of said truck 18 extended beyond the traction wheels ti, and

has mounted thereon the dump wheels '2 which track with the inclined rails an as the car is moved lorward they Wlll. en-

gage therewith, and as. they travel upward upon the same they will tend to 353.136 the rear end of the and traction wheelsitl,"

into the position of dumping, while the front wheels 8, continue to remain andiniove for ward upon the track 1.. In this manner it will be seen that if the forward pull upon the car is released when the rear part has reached its highest point upon the n .clined rail, the eight of the rear portion of said car will by gravity return sa d car to the main track, or if 'said car-Lispulled; beyond the apex of the inclinedg-h'acksii t will descend upon the opposite side i401 theg main track. The con 11mg of said; elfected by the drawar 9, which 'is oon structed witlrtheforked'end 10, which em braces thebody 4, of said cars-andehas its ends 11, pivoted to the frame work'oflsaid cars near the bottom and-midway the, ends 4 thereof, and itsforward and secured under and to the body of the precedmgear atria central point 12, thereof, and t will therafore be seen that the draft or pull of said cars .will always be on a line Without regard to the'position of the cars, which is a very important feature for cars of this class. Having thus described our invention what We claim as new and desire to secure by Letters Patent is ,In an apparatus of the class described,

I 00in prising parallel main traction rails, dump rails parallel to said traction rails and inclined upward therefrom, of dump-cars formed with an open forward end, trucks traveling upon said traction rails and supporting said cars and provided with front and rear axles and traction wheels mounted thereon, extended ends formed upon said rear axle, auxiliary wheels secured upon said extended ends and adapted to engage s-.

and travel upon said inclined dump rai a draw-bar formed with a forked rear end,

and adapted to allow said car body to pass thesides thereof.

3. The combination, with the main traction rails, of outer rails inclined upward from the road bed, of a car open at one end thereof, and having its rear axle projecting and provided with wheels adapted to engage and travel upon said inclined outer rails, a draw-bar having a bifurcated rear portion embracing and pivoted to the sides of said car midway the ends thereof.

4. The combination, with the main traction rails and the upwardly inclined parallel rails, of a car having front and rear axles provided with wheels traveling on said main rails, auxiliary outer wheels mounted .upon

the rear axle and adapted to engage and travel. upon the upwardly inclined p..rallel rails, and a forked draw-bar having the ends of its forked portion pivoted to said car mid- .way its ends.

In. testimony whereof we afiix our signatures in presence of two Witnesses.
